Snapped it into my mug before a bumpy train ride and not a single drop escaped—the seal is surprisingly snug for something so easy to pop on and off. If you're tired of sipping coffee off your own shirt, this little disc is worth the couple of bucks.
Snapped into my mug before my commute and completely forgot it was there until I took a sip. No spills on the train, and it didn't change the drinking feel at all. Exactly what I needed.
I was skeptical a tiny piece of plastic could make a difference, but it fits the mug rim perfectly and I haven't spilled a drop of coffee on my commute since. The snap-in design is genuinely foolproof, even one-handed.
